The Threat of Reputation-Based Attacks

[Humpty]

CastleCops.com is accustomed to being attacked by online crooks: The volunteer-led cybercrime-fighting group has endured nearly a month long siege by thousands of criminally-controlled PCs aimed at crippling its Web site. So when the latest attack failed to prevent legitimate users from visiting the site, the bad guys unveiled an unlikely secret weapon: bogus donations.

 

The unauthorized contributions all came in via PayPal, the online payment service owned by eBay. Some were sent via PayPal accounts that attackers had hijacked in phishing scams; others were submitted through PayPal's e-check option using compromised checking account numbers. A few donations were for as little as $1, while other fake donations ranged as high as $2,800.

 

To the victims of the stolen PayPal accounts, it looks as if CastleCops is the one stealing their money, when in reality, it's the attackers. Also, the fraudulent activity seeks to ruin their relationship with PayPal.
